LEXUS NX300h Owners Manu-
al_USA_OM78212U 6-1.Maintenance and care
Working from top to bottom, liber-
ally apply water to the vehicle body,
wheel wells and underside of the
vehicle to remove any dirt and dust.
Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
For hard-to-remove marks, use car
wash soap and rinse thoroughly with
water.
Wipe away any water.
Wax the vehicle when the water-
proof coating deteriorates. If water does not bead on a clean surface,
apply wax when the vehicle body is cool.
■
Self-restoring coat
The vehicle body has a self-restoring coat-
ing that is resistant to small surface
scratches caused in a car wash etc.
●
The coating lasts for 5 to 8 years from
when the vehicle is delivered from the
plant.
●
The restoration time differs depending on
the depth of the scratch and outside tem-
perature. The restoration time may
become shorter when the coating is
warmed by applying warm water.
●
Deep scratches caused by keys, coins,
etc. cannot be restored.
●
Do not use wax that contain abrasives. ■
Automatic car washes ●
Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door (if
equipped)
Start washing from the front of the vehicle.
Extend the mirrors before driving.●
Brushes used in automatic car washes
may scratch the vehicl e surface and harm
your vehicle’s paint. ●
Rear spoiler may not be washable in
some automatic car washes. There may
also be an increased risk of damage to
vehicle. ■
High pressure car washes ●
Do not allow the nozzles of the car wash
to come within close proximity of the win-
dows. ●
Before using the car wash, check that the
fuel filler door on your vehicle is closed
properly. ■
Note for a smart access system with
push-button start ●
If the door handle becomes wet while the
electronic key is within the effective
range, the door may lock and unlock
repeatedly. Place the key in a position 6
ft. (2 m) or more separate from the vehi-
cle while the vehicle is being washed.
(Take care to ensure that the key is not
stolen.) ●
If the electronic key is inside the vehicle
and a door handle becomes wet during a
car wash, a buzzer will sound outside the
vehicle. To turn off the alarm, lock all the
doors.
●
Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( → P.123)
■
Aluminum wheels
●
Remove any dirt immediately by using a
neutral detergent.
●
Wash detergent off with water immedi-
ately after use.
●
To protect the paint from damage, make
sure to observe the following precau-
tions.Cleaning and protecting the
vehicle exterior Perform cleaning in a manner
appropriate to each component
and its material.
